[60] fulleropyrrolidine functionalized polysiloxane as a stationary phase for capillary gas chromatography

In this paper, a new type of [60]fulleropyrrolidine functionalized polysiloxane in which the fullerene moieties were incorporated in the main polysiloxane chain was synthesized the first time and used as a stationary phase for capillary gas chromatography. It demonstrated high column efficiency (2600-2866 plates m(-1), on a 250 mu m diameter column, for naphthalene k = 3.1-3.2, 120 degrees C), a wide operational temperature range (90-360 degrees C) and outstanding thermostability. It can be used at 360 degrees C with a baseline drift of 5 similar to 8 x 10(-15) A. Benzene homologues, aromatic hydrocarbons, polar compounds such as alcohols, esters, ketones, anilines and phthalic diesters can be seperated well on this column.
